Thats the absolute worst lol. They say , "he's twice your size" then you see him and not only is he not muscular he probably weighs less than you do hahaha!
Goes to show how little people give a fuck or understand what muscle even is. Weight is weight to them muscle , fat makes no difference.
Ah....The mythical "cousin"...LOL
"You're big,,,,but he's REALLY big."
He's never bigger...ha ha ha

I often wonder, does this dude know his sister/GF/cousin is making him look like an asshole ?
